Abstract
The invention relates to a preparation method of ramie stalk antibacterial viscose fiber and the application of the ramie stalk antibacterial viscose fiber to baby diapers and adult diapers. The preparation method comprises the steps of squeezing, crushing, dipping, degrumming, acid and alkali treatment, cooking, alpha pulp preparing, after treatment and the like, is simple in preparation technology, and saves cost. The method combines inorganic bacteria prevention with natural bacteria prevention, and ensures that the ramie stalk antibacterial viscose fiber achieves the effect of double bacteria prevention through a surface layer and an inner core when being applied to paper diapers and sanitary towels, effectively prevents the growth and survival of various bacterium and pathogenic bacterium, and reduces the harm of secondary pollution of hygienic products, such as paper diapers and sanitary towels, to human body.
Description
Technical field
The present invention relates to daily living article field, particularly a kind of preparation method of ramie stalk antibacterial viscose fiber, and application on paper diaper, sanitary napkin.
Background technology
Antiseptic has four large classes at present: inorganic antiseptic, organic antibacterial agent (chemistry), natural plants antiseptic and biological antibiosis agent.And in hygiene article sector, the antimicrobial technology of application is mainly inorganic and organic anti-bacterial technology at present.But organic anti-bacterial is mainly that chemicals is antibacterial, very large to the side effect of ambient influnence and human body, not water-wash resistance, poor stability; In addition, inorganic antibacterial mainly uses metal ion antimicrobial technology, as Nano Silver, zinc, copper ion etc., expends the energy more, moreover be scarce resource when manufacture, and collection, process can cause pollution in various degree to environment.Therefore, be badly in need of a kind of antibacterial ability of development strong, to human body nonhazardous effect, and the free of contamination anti-biotic material of production process, for solving the antibacterial difficult problem of hygiene article sector.
Ramie is China's special product, and ramie is perennial root herbaceous plant, is described as " China's grass; middle national treasure " by the world, has antibacterial, ventilative, nice and cool, anticorrosion, mildew-resistant, the functions such as absorbing sweat, universally acknowledged " king of natural fabric ", is important textile fabric crop, the active cavity structure feature that ramie is exclusive, its filament is long, so have superior gas permeability and conductivity of heat, water suction is many and loose wet fast, has cooling feeling.Ramie contains the trace elements such as the pyridine of giving repeated exhortations, pyrimidine and purine simultaneously, and Escherichia coli, staphylococcus aureus, Pseudomonas aeruginosa are played to inhibition, has natural bacteriostatic, anti-mite, deodorant function.Ramie has superfine hollow structure, has powerful adsorption capacity.Therefore, ramie is the desirable anti-biotic material as the amenities such as sanitary napkin, paper diaper inner core.At present, on market, yet there are no and utilize ramie to manufacture the report of the amenities of sanitary napkin, paper diaper etc. for raw material, in people's life, need a kind of taking ramie stalk as raw-material, there is antibiotic property and gas permeability, loose moist personal hygiene article strong, that anticorrosive mildewproof is effective.
Summary of the invention
The object of this invention is to provide a kind of preparation method of ramie stalk antibacterial viscose fiber, and application on paper diaper, sanitary napkin.Inner core material using ramie stalk antibacterial viscose fiber of the present invention as the amenities such as paper diaper, sanitary napkin, its antibiotic property, gas permeability, loose moist strong, be a kind of anticorrosion, anti-biotic material that anti-mold effect is splendid.
